[CMake] CMake 3.5.0-rc1 install is missing dependencies

Thu Feb 4 11:00:27 EST 2016

BTW - I am seeing the segmentation fault at the same location on 3 different systems:

SUSE Linux Enterprise Server 11 (x86_64)
CentOS Linux release 7.1.1503 (Core)
Red Hat Enterprise Linux Workstation release 6.7 (Santiago)

My project is not open source and I cannot distribute our source code.

I recompiled cmake-3.5.0-rc1 from sources with debug symbols and ran under a debugger. I located this failure:

Thread 1 stopped in cmPolicies::PolicyMap::Get with signal SIGSEGV (Segmentation fault).
Reason/Origin: address not mapped to object (attempt to access invalid address)

In cmInstallCommand.cxx, line 1376

cmTarget* tgt = this->Makefile->FindTarget(te->TargetName);

is setting tgt to a NULL pointer (0x0) that is dereferenced in the next line (stack location #5)

tgt->GetPolicyStatusCMP0022()

This is causing the segfault.

I'm working on a reproducer.  For now, all I can say is that it looks like the segmentation fault occurs on this command:

install( EXPORT foo-targets
  DESTINATION foo
  EXPORT_LINK_INTERFACE_LIBRARIES )

-kt

What project are you configuring?

Can you provide a CMakeLists.txt file that reproduces this crash?

Thanks,
